06:59 | <dragonbch> hello friends
| |
07:00 | yet I have a problem with ltsp-build-client
| |
07:00 | :(
| |
07:01 | brites has joined #ltsp | |
07:02 | <alkisg> dragonbch: what problem?
| |
07:02 | brites has joined #ltsp | |
07:03 | <dragonbch> I'm trying run the line with argument for it donwload the component of a repo in my hd :
| |
07:03 | ltsp-build-client --base /opt/ltsp/ --arch i386 --dist lenny --mirror ftp://192.168.74.3/debian

| |
07:03 | for example
| |
07:04 | the directorie /opt/ltsp/i386 is clear
| |
07:05 | sorry my english not is good
| |
07:05 | <alkisg> I don't think that's a valid mirror line
| |
07:05 | <dragonbch> I speak spanish
| |
07:05 | <alkisg> http://ts.sch.gr/repo stable main
| |
07:05 | You need something like that ^^^
| |
07:06 | <dragonbch> the problem is that I am cut by a proxy
| |
07:06 | <alkisg> (unless debian ltsp discovers the components automatically, I'm not sure)
| |
07:06 | <dragonbch> and I not have access
| |
07:06 | :s
| |
07:06 | <alkisg> doesn't --http-proxy help there?
| |
07:07 | <dragonbch> no
| |
07:08 | try2free has left #ltsp | |
07:09 | <dragonbch> only I have the repository on my hd
| |
07:09 | <alkisg> Then you need to tell debootstrap to find your repository
| |
07:09 | That's not ltsp-related
| |
07:10 | E.g. you can use apt-file in your sources...
| |
07:11 | The --mirror takes effect *after* the initial chroot is generated
| |
07:11 | ltsp-build-client calls debootstrap to generate the initial chroot
| |
07:11 | So you need to enable debootstrap to find the necessary packages, e.g. with apt-file or some other way
| |
07:13 | <dragonbch> mmm

07:50 | <Gadi> alkisg: ping
| |
07:50 | <alkisg> gadi, pong
| |
07:50 | <Gadi> hey - I found the instability in squashfs that stgraber must have seen
| |
07:50 | evidently lucid's kernel has issues compressing fragments
| |
07:51 | as soon as I use a -noF, I have no more problems
| |
07:51 | kusznir has joined #ltsp | |
07:52 | <Gadi> it kills the compression, tho
| |
07:52 | 171MB goes to 295MB
| |
07:52 | <alkisg> Isn't that what stgraber put in ltsp-update-image.conf?
| |
07:52 | NO_COMP="-noF -noD -noI -no-exports"
| |
07:52 | * Gadi wonders why the liveCD team hasn't seen this | |
07:53 | <Gadi> alkisg: yeah, well he turns off everything
| |
07:53 | but, I have found problems only with fragments
| |
07:53 | <alkisg> ...but the live cd works fine, though, so?!
| |
07:53 | Ah got it
| |
07:53 | <Gadi> with everything turned off, you go to well over 500MB
| |
07:53 | I don't know that the liveCD does work fine
| |
07:54 | you only see it when you hit a file that is on a fragment
| |
07:54 | the liveCD may have gotten lucky?
| |
07:54 | :)
| |
07:54 | <alkisg> I've installed lucid a dozen times and I heard many people installing lucid with no (file related) problems so far... How often would that happen?
| |
07:54 | Maybe the block size matters?
| |
07:54 | <Gadi> well, here's an example
| |
07:55 | so, in one of my squashfs images, the file /usr/bin/groups was on a fragment
| |
07:55 | so, if I booted to a shell and did something like:
| |
07:55 | md5sum /usr/bin/groups
| |
07:55 | I would get squashfs errors
| |
07:55 | but, if I did md5sum <some other file>, it would be ok
| |
07:56 | so, as long as nothing needed to run /usr/bin/groups,
| |
07:56 | everything was fine
| |
07:56 | remember, if you use the liveCD to install, it only runs one or two programs in the liveCD itself
| |
07:57 | the OS is installed from uncompressed debs on the CD
| |
07:57 | it would be interesting to boot a liveCD, open a terminal window, and run: md5sum /usr/bin/*
| |
07:57 | or /usr/sbin/*
| |
07:58 | and see if there are errors
| |
07:58 | <alkisg> That's easy to do, moment...
| |
07:59 | kusznir has quit IRC | |
08:02 | <alkisg> Gadi, both dirs check out fine
| |
08:02 | <Gadi> hmm
| |
08:03 | I wonder how they are squashing their fs
| |
08:03 | <alkisg> With just 1 processor?! :)
| |
08:03 | <Gadi> nah - I tried that
| |
08:03 | it didn't help
| |
08:03 | <alkisg> Hrm, ogra, any clues here? ^^^
| |
08:04 | (what is the command that is used for compressing the ubuntu live cd)
| |
08:04 | <ogra> look in the livecd-rootfs package source
| |
08:04 | <alkisg> Ty
| |
08:04 | <ogra> simply mksquashfs
| |
08:05 | kusznir has joined #ltsp | |
08:06 | <Gadi> hmm, seems the regular CD simply adds a -sort
| |
08:08 | <alkisg> So maybe sorting forces mksquashfs to use some kind of caching, which helps
| |
08:09 | Gadi can you try with a sort file with just 1 line in it: /path/to/not/existing/file 32767
| |
08:11 | !compiz

09:50 | <Gadi> alkisg: do you know if nbd-client is killed and restarted in the rootfs after the switch from initramfs?

09:51 | <alkisg> Gadi, I'm not sure. I think that was the case before nbd-proxy, but I haven't checked the source at that point...
| |
09:51 | <Gadi> ok
| |
09:51 | sbalneav has joined #ltsp | |
09:51 | <Gadi> yeah, I have not found anything in the source to suggest it anymore

09:53 | <Gadi> alkisg: I can't decide if the problem is nbd or squashfs

09:53 | :)
| |
09:53 | or door #3
| |
09:53 | :)
| |
09:53 | <alkisg> Hmmm
| |
09:54 | <Gadi> but, you get tons of errors when the file it can't read is /lib/libudev ;)
| |
09:55 | it seems to be different files every boot, BUT it also seems to be the same file for any given boot
| |
09:55 | which says to me it is an nbd thing
| |
09:58 | <alkisg> If you start a standalone machine, connect to the server with nbd-client, and dd the whole drive 2 times, and compare them? Won't that tell you if it's an nbd problem or not?
| |
10:01 | <thunsucker> Gadi: door behind #3 might be a Zonk

12:50 | <elias_a> Good evening!
| |
12:51 | I am trying to make a demo server out of laptop with this documentation: https://help.ubuntu.com/community/UbuntuLTSP/LaptopDemo
| |
12:51 | I am experiencing odd problems.
| |
12:52 | My wlan seems to die when I plug in the client to the LAN NIC.
| |
12:52 | <alkisg> elias_a: what problems? And, what's your actual use? Maybe proxydhcp would be better suited in your case?
| |
12:52 | wlan dies ==> maybe a routing problem?
| |
12:52 | <elias_a> alkisg: Could be.
| |
12:52 | <alkisg> Are you using network manager?
| |
12:52 | <elias_a> Yes.
| |
12:53 | <alkisg> Did you declare a static connection for eth0 with no routes?
| |
12:53 | (no gateways, I mean)
| |
12:53 | <elias_a> Is it OK that my wlan is eth1 instead of wlan0
| |
12:53 | <alkisg> Sure
| |
12:54 | <elias_a> alkisg: That might be the problem - I'll check.
| |
12:54 | <alkisg> So you should have eth0 = static with no route, eth1 = dhcp (networkmanager)
| |
12:55 | <elias_a> no route meaning there is no gateway nor dns?
| |
12:55 | <alkisg> No gateway
| |
12:55 | ...and you don't need dns either for that connection
| |
12:57 | Also if you're trying to use /etc/network/interfaces to make eth0 == static, there was a bug with networkmanager, connections disappeared when you tried to do that
| |
12:57 | <elias_a> Is this OK for interfaces? http://pastebin.com/uExtit9G
| |
12:57 | <alkisg> I don't think it's solved yet
| |
12:57 | Is that Karmic?
| |
12:57 | <elias_a> Ahh.. bloody hell.
| |
12:57 | <alkisg> *system connections, that is. You can use user connections though
| |
12:58 | I.e. in network manager you should *not* check the "make this connection available for all users" button
| |
12:58 | <elias_a> Yep - it's Karmic.
| |
12:58 | <alkisg> It's ok. You don't need network nor broadcast, but it doesn't hurt to put them there
| |
12:58 | <atkuepker> ick NM. step #1 of our deployment document: aptitude remote network-manager
| |
12:59 | <alkisg> elias_a: So just make a user connection in network manager, not a system connection
| |
12:59 | <elias_a> OK.
| |
12:59 | <alkisg> atkuepker: it's handy for wireless networks, laptops etc though...
| |
12:59 | elias_a: another, probably better way to do it, is to completely stop using /etc/network/interfaces
| |
13:00 | <elias_a> atkuepker: Cannot live without NM.
| |
13:00 | <alkisg> ...and make eth0 == static from within network manager
| |
13:00 | <atkuepker> agreed, for laptops. We had horrible difficulties with it until we yanked it off the servers.
| |
13:00 | denisesball has joined #ltsp | |
13:01 | <elias_a> atkuepker: Correct - in my case it is a must. Lots of travelling and using 2 different VPNs.
| |
13:01 | alkisg: good idea.
| |
13:01 | <alkisg> elias_a: the bug I'm referring to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/391040
| |
13:02 | If you're experiencing the same, do post there
| |
13:02 | <elias_a> The wlan was not a system connection.
| |
13:02 | <alkisg> OK, was the connection lost from the menu?
| |
13:02 | Or it just wasn't working right?
| |
13:03 | <elias_a> It was in the menu but not working.
| |
13:04 | <alkisg> OK, different problem then, ignore the link above
| |
13:04 | <elias_a> The funny thing is that wlan stops working after plugging the client or a switch to the NIC
| |
13:04 | jcastro has quit IRC | |
13:04 | <alkisg> Check if it's working now that you don't have a route in eth0
| |
13:05 | jcastro has joined #ltsp | |
13:05 | <elias_a> Even if the NIC is definned in interfaces file :)

13:05 | I'll try.

13:06 | <epaphus> Hello guys, i have an LTSP network (new) where the clients are booting VERY slow.. the dhcp lease, the tftp download.. once it does that everything is ok
| |
13:06 | It can take like about 5 min
| |
13:06 | to boot 1
| |
13:07 | the switch is not saturated
| |
13:07 | what could be the problem? The server doesnt have anything relevant in /var/log/daemon , and messages
| |
13:07 | <alkisg> The dhcp lease?
| |
13:07 | <epaphus> alkisg, yeah. Where each thin client gets the IP.. that part is super slow
| |
13:08 | <alkisg> The first lease? From the PXE stack, before even loading pxelinux?
| |
13:08 | <epaphus> alkisg, correct
| |
13:08 | <alkisg> Doesn't it timeout at 60 secs at that point?
| |
13:08 | <epaphus> yes, when i said 5 min i meant it between that lease and the tftp download
| |
13:08 | thats whats taken a long time
| |
13:09 | <alkisg> I'm not sure I got this right. So, is it a dhcp problem or a tftp problem?
| |
13:09 | (or both?)
| |
13:09 | <epaphus> both . both processes are very slow
| |
13:09 | <alkisg> If it gets an IP address and *then* it delays, it's a tftp problem
| |
13:10 | <epaphus> where is the log for tftp ?
| |
13:10 | <alkisg> distro/version?
| |
13:10 | <epaphus> ubuntu 9.10
| |
13:10 | <alkisg> (brb)
| |
13:11 | For tftp you'd need to put --verbose in /etc/default/tftpd-hpa
| |
13:11 | <epaphus> ahhh ok... thank you ill check that :)

13:15 | <alkisg> epaphus: I've seen several cases where Ubuntu's pxelinux.0 had this problem, but I never saw dhcp3-server causing slow boots. If it's _only_ after pxelinux is loaded, try downloading the latest one from sid, as Ubuntu's is ancient...
| |
13:23 | <epaphus> alkisg, thank you
| |
13:23 | it is intermittent
| |
13:23 | all of the sudden all is well
| |
13:23 | :(
| |
13:28 | <komunista> epaphus: only idea, do you have only one DHCP server on netvork? I was similar problem (no PXE), and I find then second DHCP server (bad interface binding)...
| |
13:29 | <elias_a> alkisg: This is really funny - if I define the NIC in /interfaces, the wlan that is taken care by NM dies.
| |
13:29 | Shows OK in the appled but bits&bytes won't move.
| |
13:30 | I'll try to define the NIC in NM
| |
13:30 | <alkisg> elias_a: type `route -n` at that point
| |
13:30 | To see if everything is OK with your routes...
| |
13:30 | But yeah, defining it within NM is a better way to do it :)
| |
13:33 | <denisesball> hey all, i'm trying to connect to my ltsp server from my PC and i thought xdmcp over xnest would work but the screen is just black
| |
13:33 | i want to be able to login to the ltsp person just as a user would
| |
13:38 | <epaphus> komunista, yes only one DHCP server
| |
13:39 | <komunista> epaphus: I'm sorry :-)
| |
13:39 | <epaphus> np
| |
13:41 | <alkisg> denisesball: ltsp 5 doesn't use xdmcp
| |
13:41 | If you enabled it on your server then it should work, but that's unrelated to ltsp
| |
13:41 | <denisesball> alkisg: ok, i think i'm seeing that now. so is there a way to connect with tsclient or something similar from an existing desktop that doesnt need to boot the image?
| |
13:41 | <elias_a> Funny - connecting NIC kills the wlan connection even if nic is defined in NM.
| |
13:42 | <denisesball> just so i can test things from my machine
| |
13:42 | <alkisg> denisesball: whatever other method applies to standard linux desktops. E.g. I'm using neatx currently.
| |
13:44 | elias_a: upload your nm files to pastebin if you want; for system connections they're in /etc/NetworkManager/system-connections, for user-only connections I don't know but you can google it...
| |
13:44 | (somewhere in ~/.config or ~/.local...)
| |
13:49 | <denisesball> alkisg: never heard of neatx
| |
13:49 | <alkisg> denisesball: have you heard of nx or freenx?
| |
13:49 | <elias_a> alkisg: This is what the routes look like in 1) non functioning state and 2) functioning state.
| |
13:49 | http://pastebin.com/5PCDUMJd
| |
13:51 | 1) is caused with the same setup by only plugging a cable into the NIC.
| |
13:52 | <alkisg> elias_a: they need to be in different subnets
| |
13:52 | Don't use the same subnet for both eth0 and eth1
| |
13:53 | Put eth0 in 192.168.1.x or somethine like that.
| |
13:53 | <denisesball> alkisg: yeah i use NX, but wouldnt that require installing an NX server on the ltsp server?
| |
13:53 | <alkisg> denisesball: yes, neatx-server
| |
13:53 | <denisesball> can i simply connect the same way the terminals?
| |
13:53 | do
| |
13:53 | <alkisg> It's the latest free nx server implementation from google
| |
13:53 | <denisesball> like ldm/SSH?
| |
13:53 | <alkisg> denisesball: the terminals connect with ssh -X or with some xauth magic when DIRECTX is true
| |
13:54 | <denisesball> right, i figured i would just do that, but skipping the PXE boot
| |
13:54 | <alkisg> So sure, try ssh -X, if that's speedy enough for you then you don't need nx
| |
13:55 | You won't get a full session though...
| |
13:55 | <denisesball> i did try that, but i dont know what to run after i logged in
| |
13:55 | <alkisg> Ah, and xnest...
| |
13:56 | Hmm yeah I got it
| |
13:56 | <denisesball> xnest isnt installed on the ltsp server though
| |
13:58 | <elias_a> alkisg: True :) Stupid me :)
| |
13:58 | (too tired - I guess)
| |
13:58 | <alkisg> elias_a: don't worry you're not the first that got hit by that ;)
| |
14:01 | <elias_a> alkisg: :)
| |
14:01 | <denisesball> alkisg: so what would i run once I'm ssh'd with the X11 forwarding? how do i get ldm?
| |
14:02 | <alkisg> denisesball: ldm runs on the client, not on the ltsp server
| |
14:02 | So I don't know how you'd get it...
| |
14:03 | <denisesball> hm, this seems like it should be easier
| |
14:05 | i suppose i could enable xdmcp for GDM instead of LDM
| |
14:08 | yep, that worked perfectly alkisg
| |
14:08 | gksudo cp /usr/share/doc/gdm/examples/custom.conf /etc/gdm/
| |
14:08 | gksudo gedit /etc/gdm/custom.conf
| |
14:08 | Add the line “Enable=true” after the “[xdmcp]” line
| |
14:08 | restart gdm, done
| |
14:09 | <alkisg> Yup... trivial
| |
14:09 | ldm on the clients without installing it would be tricky though ;)
| |
14:10 | <denisesball> yeah i didnt really make the connection that gdm was still on there
| |
14:10 | <alkisg> ldm *isn't* installed on the server
| |
14:10 | There's only gdm
| |
14:10 | <denisesball> right, i gotcha
| |
14:10 | vagrantc has joined #ltsp | |
14:11 | <denisesball> this is fast enough, i just wanna be able to login and see what techs are seeing when they have problems
| |
14:11 | although i keep getting disconnected every few minutes for some reason...
| |
14:12 | <alkisg> xdmcp is the fastest of all for lan connections
| |
14:12 | <vagrantc> xdmcp isn't any faster than ldm with LDM_DIRECTX=True
| |
14:12 | <alkisg> vagrantc: he wants to use it in non-ltsp clients
| |
14:12 | <vagrantc> except for initial login
| |
14:13 | <denisesball> vagrantc: do you know of a way to connect like that from a regular desktop?
| |
14:13 | <alkisg> So ldm isn't an option...
| |
14:13 | <denisesball> yeah thats i was curious about
| |
14:32 | br_ain has quit IRC | |
14:34 | <Gadi> denisesball: you can use a script like this http://pastebin.com/jNtyV7AL , modify the LDM_SERVER IP, add the ssh host key of that IP to your known_hosts file, and apt-get install xnest ldm and you can ldm from your desktop, if you like
| |
14:35 | it won't run through everything that the client does, but it will be similar
| |
14:36 | <denisesball> Gadi: interesting, thanks!
| |
14:36 | did you write that?
| |
14:37 | <Gadi> one of the TODOs I always had on the back-burner was to make ldm standalone like that. I copied the screen script and just modified it
| |
14:37 | <denisesball> installing ldm locally wont mess with my gdm right?
| |
14:37 | <Gadi> one of these days, we should do it cleanly
| |
14:37 | nope
| |
14:37 | it's not a real display manager
| |
14:37 | :)
| |
14:39 | denisesball: you may also want to look into setting up VNC shadowing on the clients
| |
14:39 | then, as long as they are booting to a login screen, you can vnc into them and log in directly from the thin client
| |
14:39 | <denisesball> Gadi: yeah that may be an option, but not really what I was looking for right now
| |
14:40 | script doesnt appear to work for me
| |
14:41 | <Gadi> what does it do?
| |
14:41 | (run as sudo btw)
| |
14:42 | <denisesball> yeah i noticed that
| |
14:42 | when running as sudo, nothing happens
| |
14:42 | hangs there for a bit and back to the prompt
| |
14:42 | <Gadi> you have ldm and xnest installed?
| |
14:42 | <denisesball> yeah
| |
14:42 | $ dpkg -l | egrep 'xnest|ldm'
| |
14:42 | ii ldm 2:2.0.38-0ubuntu5 LTSP display manager
| |
14:42 | ii ldm-ubuntu-themes 2:2.0.38-0ubuntu5 Themes for the LTSP Display Manager
| |
14:42 | ii libwildmidi0 0.2.2-2 software MIDI player library
| |
14:43 | ii xnest 2:1.6.0-0ubuntu14.1 Nested X server
| |
14:43 | pmatulis has quit IRC | |
14:43 | <Gadi> and you changed LDM_SERVER in the script to point tours?
| |
14:43 | er, to yours?
| |
14:43 | <denisesball> yep
| |
14:43 | $ cat ldm.sh | grep LDM_SERVER
| |
14:43 | LDM_SERVER=10.30.40.149
| |
14:43 | same IP i use with xdmcp
| |
14:44 | i have an idea
| |
14:44 | do i have to be on the same term server subnet?
| |
14:44 | cuz thats the outside IP
| |
14:45 | do i have to be on the network ltsp gives out dhcp addresses?
| |
14:45 | scottmaccal has quit IRC | |
14:45 | <Gadi> port 22 is open?
| |
14:45 | <denisesball> yep, im ssh'd into it
| |
14:46 | <Gadi> does it hang for more than 5 seconds?
| |
14:47 | <denisesball> yeah definitely
| |
14:47 | $ time sudo ./ldm.sh
| |
14:47 | real 0m15.124s
| |
14:47 | user 0m0.030s
| |
14:47 | sys 0m0.030s
| |
14:47 | $
| |
14:49 | <Gadi> weird. works for me
| |
14:50 | does sudo Xnest :2 work?
| |
14:50 | (maybe Xnest is broken there for some reason)
| |
14:51 | <denisesball> depends what you mean by "works"
| |
14:51 | a window with a black screen pops up
| |
14:51 | does it matter that im on a dual display?
| |
14:51 | <Gadi> with an X cursor?
| |
14:51 | <denisesball> no just completely black
| |
14:51 | <Gadi> ah, right
| |
14:51 | same here
| |
14:51 | ok, thats good
| |
14:52 | how about: sudo xinit -- /usr/bin/Xnest :2
| |
14:53 | <denisesball> yeah brings up a mostly black window with a usable terminal in the corner
| |
14:54 | <Gadi> and: sudo xinit /usr/sbin/ldm -- /usr/bin/Xnest :2
| |
14:56 | cliebow has quit IRC | |
14:56 | <denisesball> yep, works
| |
14:56 | looks like the ldm screen
| |
14:56 | <Gadi> hmm
| |
14:57 | maybe a cut/paste problem with the script I pasted?
| |
14:57 | <denisesball> my network idea isnt right?
| |
14:57 | ill download instead of copy/paste
| |
14:57 | <Gadi> yeah, try that
| |
14:58 | I would have expected you to at least get the ldm screen
| |
14:58 | if it were a network problem, you may have issues logging in
| |
14:59 | <denisesball> well like i said, im hitting the outside interface, not the inside one the ltsp clients hit
| |
15:01 | <Gadi> right - but the login screen should come up anyway
| |
15:01 | it's just a gtk greeter on the local side
| |
15:02 | <denisesball> kinda weird now, wont execute the downloaded one even renames as a .sh with executable permissions
| |
15:02 | using sh i get output not at least
| |
15:02 | $ sudo sh ltsp.sh
| |
15:02 | : not found:
| |
15:02 | : not found:
| |
15:02 | : not found:
| |
15:02 | : bad trapTERM
| |
15:02 | ltsp.sh: 1: cleanup: not found
| |
15:04 | <Gadi> that's just at a regular terminal shell on your local machine?
| |
15:04 | ie a gnome-terminal?
| |
15:04 | <denisesball> yep
| |
15:04 | i dont know why i cant ./ it now though
| |
15:05 | oops
| |
15:06 | evilx has quit IRC | |
15:06 | <denisesball> nope, looks good
| |
15:06 | odd
| |
15:06 | <Gadi> that is weird
| |
15:06 | can you try opening a new terminal window
| |
15:06 | maybe the environment got messed up?
| |
15:07 | <denisesball> yeah same thing
| |
15:07 | my other scripts work fine
| |
15:08 | dragonbch has joined #ltsp | |
15:10 | <denisesball> i re copied and pasted into the old one i used and same result
| |
15:10 | dunno why making a new one is so weird
| |
15:10 | <Gadi> weird
| |
15:10 | I just d/l'd the pastebin
| |
15:10 | <dragonbch> alkisg the client pc sey me:
| |
15:10 | TFTP....
| |
15:10 | tftp: open timeout
| |
15:10 | <Gadi> and diffed against what I pasted
| |
15:10 | and it says every line is different
| |
15:11 | <dragonbch> say*
| |
15:11 | <denisesball> wtf
| |
15:11 | <Gadi> !pastebot
| |

| |
15:11 | <denisesball> i just clicked raw and copied and pasted that the first time
| |
15:13 | <Gadi> http://ltsp.pastebin.com/533JHFN2
| |
15:13 | let's try that
| |
15:13 | <denisesball> k
| |
15:13 | should i click download then?
| |
15:14 | Gadi: same result for me when clicking download
| |
15:15 | <Gadi> cut/paste from raw worked better
| |
15:15 | <denisesball> this is the strangest thing ever
| |
15:16 | yeah copy/paste raw seems to work better
| |
15:16 | still same result though
| |
15:16 | just hangs there and eventually get me back to prompt
| |
15:17 | <Gadi> weird
| |
15:17 | <denisesball> would it matter that i ran it as user before sudo the first time?
| |
15:17 | could there be stale stuff around?
| |
15:17 | <Gadi> I don't think so
| |
15:18 | <denisesball> i wish i could see what its dying on
| |
15:19 | <Gadi> denisesball: at the top of the script (after the first line) put a line that reads: set -x
| |
15:19 | then, run it again
| |
15:21 | <denisesball> + xinit /usr/sbin/ldm -- /usr/bin/Xnest :2 -auth /var/run/ldm-xauth-RNsWRwXOc/Xauthority -br
| |
15:21 | that line
| |
15:21 | just hangs
| |
15:21 | then eventually runs the cleanup
| |
15:22 | /usr/share/ltsp/xinitrc
| |
15:22 | in your script
| |
15:22 | that doesnt exist for me
| |
15:22 | <Gadi> thats ok
| |
15:22 | <denisesball> its in /etc/X11/xinit/xinitrc
| |
15:22 | ok
| |
15:22 | <Gadi> while its hanging, can you check in another window for the existence of /var/run/ldm-xauth-RNsWRwXOc/Xauthority
| |
15:22 | <denisesball> yeah i did that already lol
| |
15:23 | it did
| |
15:23 | exist
| |
15:23 | do u know what
| |
15:23 | while its hanging there
| |
15:23 | i pasted the exact same command in another tab, and the window does pop up
| |
15:27 | so i have a bunch of output from the xinit command its trying to run if i try it in that other window which its hanging if u wanna see
| |
15:28 | <Gadi> sure, you can paste it
| |
15:29 | <denisesball> http://pastebin.com/6Wcc2FYm
| |
15:29 | i ran that while it was hanging on that same command with the script
| |
15:30 | <Gadi> that's just at a login screen?
| |
15:30 | <denisesball> it doesnt actually connect
| |
15:31 | but it gives me output
| |
15:31 | unlike the script
| |
15:31 | <Gadi> ah, maybe in the script, remove the >/dev/null 2>&1 at the end of the xinit line
| |
15:31 | also, are you running inside a virtual machine?
| |
15:32 | <denisesball> oh duh, i shouldve seen that
| |
15:32 | no, im not
| |
15:32 | <Gadi> are you running on a thin client?
| |
15:32 | <denisesball> + xinit /usr/sbin/ldm -- /usr/bin/Xnest :2 -auth /var/run/ldm-xauth-HALVthLYs/Xauthority -br
| |
15:32 | No protocol specified
| |
15:32 | Fatal server error:

15:32 | Unable to open display ":0.0".
| |
15:32 | thats what i see now
| |
15:32 | no, not a thin client
| |
15:32 | giving up.
| |
15:32 | xinit: No such file or directory (errno 2): unable to connect to X server
| |
15:32 | xinit: No such process (errno 3): Server error.
| |
15:32 | thats the end before the cleanup
| |
15:33 | <Gadi> in a terminal, type: xhost +localhost
| |
15:33 | and then try again
| |
15:33 | <denisesball> worked!
| |
15:34 | <Gadi> what distro are you on, btw?
| |
15:34 | <denisesball> ubuntu 9.04
| |
15:34 | i do get a login screen now, but it doesnt log in :(
| |
15:35 | shoot, hang on
| |
15:35 | <Gadi> did you add the ssh public key of the server you are connecting to?
| |
15:35 | * vagrantc recommends tcp/ip over carrier pidgeon | |
15:35 | <denisesball> im sorry, the script still fails, i ran that command separately andit worked
| |
15:35 | im still getting that same error with your script
| |
15:35 | + xinit /usr/sbin/ldm -- /usr/bin/Xnest :2 -auth /var/run/ldm-xauth-hqPTxWImO/Xauthority -br
| |
15:35 | No protocol specified

| |
15:36 | ogra_cmpc has quit IRC | |
15:36 | <denisesball> xinit: No such process (errno 3): Server error.
| |
15:36 | still got that
| |
15:36 | <Gadi> try: xhost +
| |
15:36 | and then: sudo <script>
| |
15:36 | <denisesball> looks like it worked that time
| |
15:37 | trying to login, taking a long time
| |
15:37 | and eventually it died
| |
15:37 | <Gadi> are you over a wan?
| |
15:37 | <denisesball> no, actually connected to the same switch in my office
| |
15:38 | alkisg has quit IRC | |
15:38 | <denisesball> hangs at "verifying password" and eventually dies
| |
15:38 | <Gadi> ok, try this (temporarily)
| |
15:38 | edit (with sudo): /etc/ssh/ssh_config and add the line: StrictHostKeyChecking no
| |
15:38 | then, try again
| |
15:40 | johnny has left #ltsp | |
15:40 | <denisesball> that did work
| |
15:41 | wait a sec
| |
15:41 | Eghie has joined #ltsp | |
15:41 | <denisesball> no, i put the key in .ssh/known_hosts
| |
15:41 | johnny has joined #ltsp | |
15:42 | <Gadi> denisesball: since you run it as sudo, it actually needs to be in /root/.ssh/known_hosts
| |
15:42 | <denisesball> i did that too
| |
15:42 | <Gadi> OR in the global /etc/ssh/ssh_known_hosts
| |
15:43 | <denisesball> i put the dsa and rsa keys in both ~/.ssh/known_hosts as well as /root/.ssh/known_hosts
| |
15:43 | <Gadi> are you prompted when you do: sudo ssh <ip>
| |
15:44 | <denisesball> just for password
| |
15:44 | $ sudo ssh 10.30.40.149
| |
15:44 | root@10.30.40.149's password:
| |
15:44 | <Gadi> ah, then that should be good
| |
15:44 | try removing the line in ssh_config and see if it still works
| |
15:44 | <denisesball> yep i did
| |
15:45 | still works
| |
15:45 | <Gadi> good
| |
15:45 | <denisesball> whew
| |
15:45 | that was fun
| |
15:45 | <Gadi> I'll say
| |
15:45 | whew
| |
15:46 | <denisesball> only think is i think its making the window the width of one of my displays, but the actual resolution inside the window the width of my whole display
| |
15:46 | so i can basically only see half of it
| |
15:46 | but no biggie
| |
15:46 | <Gadi> well, you can man Xnest
| |
15:46 | and adjust to taste
| |
15:47 | (on the last line of the script)
| |
15:47 | <denisesball> yep, i figured
| |
15:47 | thanks a ton for the help Gadi, nice to have options
| |
15:48 | <Gadi> we're all about options here
| |

15:51 | <denisesball> would you recommend it in its current state for a large environment? i know they are rewriting a lot of it.
| |
15:51 | <Gadi> well, it's a bit quirky to set up
| |
15:51 | I was fortunate to have stgraber around on irc
| |
15:51 | at the time
| |
15:51 | <denisesball> seems like it, a lot of the docs are very confusing
| |
15:52 | is it possible to make the management servers redundant?
| |
15:52 | <Gadi> I am not sure if they are working on making it less quirky to set up or just less quirky to use through the web interface
| |
15:52 | everything can be made redundant
| |
15:52 | <denisesball> couldnt find much info about that at all
| |
15:52 | <Gadi> stgraber will talk you r ear off about their 5000 thin client deployment in Canada ;)
| |
15:53 | <denisesball> that would be the attraction for me
| |
15:53 | <Gadi> ltsp-cluster itself does not do all the redundancy
| |
15:53 | there's some left up to the imagination
| |
15:53 | for example:
| |
15:53 | the web interface uses postgres db as a backend
| |
15:54 | well, say you want two servers running the web interface and db (for redundancy)
| |
15:54 | hersonls has quit IRC | |
15:54 | <Gadi> well, now you need to make your postgres dbs redundant
| |
15:54 | ltsp-cluster doesn't do that
| |
15:54 | <denisesball> right
| |
15:54 | <Gadi> you need to decide how you plan to do that on ur own
| |
15:55 | <denisesball> let me explain our environment real quick, maybe you can offer some advice
| |
15:56 | i inherited a 100+ terminal existing ltsp environment, theyre on Debian 4 with iceweasel, everything is so old and out of date, buggy, unstable etc. im planning to replace the whole thing. the way they work is each section of cubes (maybe like 25 at a time) are on a particular vlan that connects to 1 of 4 or 5 ltsp servers
| |
15:57 | every ltsp server has all the home directories mountes via NFS
| |
15:57 | mounted*
| |
15:57 | so im looking into ltsp-cluster as an option to balance the users instead of dedicating them to a particular server
| |
15:57 | but really its easy to get around if one of those servers go down, just change the VLAN the switch is on
| |
15:58 | i liked the idea of load balancing the users across the servers instead of dedicating them, but i dont want to add much more complexity and especially less redundancy if the master/root servers go down
| |
15:58 | /rant
| |
15:59 | <Gadi> hehe
| |
16:00 | well, ltsp-cluster has some very nice features to it, but it does add complexity
| |
16:00 | <denisesball> when i said "really it's easy..." i was referring to the existing setup obviously
| |
16:00 | just changing the VLAN is easy for it to PXE boot to
| |
16:02 | i dont wanna have to make more servers redundant manually just to get load balancing, i could really load balance them myself with the network load balancer if i really wanted to
| |
16:02 | plus the fact that they are rewriting it is discouraging
| |
16:03 | <Gadi> well, I think as more people use it and contribute to it, it will improve
| |
16:03 | like anything else
| |
16:03 | <denisesball> yeah of course, as goes with any open source project. just wondering if its a good idea to put into production as it is now
| |
16:03 | sounds less likely the more i read
| |
16:04 | <Gadi> well, I would say for now, view it as a platform that you can start with if you don't want to implement the same thing from scratch
| |
16:04 | but don't think you will just apt-get install ltsp-cluster and have ootb redundancy
| |
16:05 | and speaking about scratch, I need to write a poor-man's sabayon, since xephyr seems to segfault on this darn system...

16:08 | <denisesball> Gadi: thanks again for the help, im out for today
| |
16:09 | <komunista> Gadi: I'm sorry, I have one question
| |
16:09 | I read some things abou ltsp-cluster and interesting for me is web interface to monitoring clients, it is possible use this interface without cluster, please?
| |
16:13 | <Gadi> komunista: the interface that does the monitoring also does the configuring, I think if you use it, you will need to use it to configure as well as monitor
| |

16:17 | <komunista> hmm, I must read osme about configuring by this interface :-) (I don't understand what is problem with this), thanks

18:52 | <Ahmuck-Sr> i'm trying to boot another set of ltsp clients to see how well they work, however they don't have a pxe boot option which means i'll have to create a etherboot cdrom. any hints

19:09 | <Ahmuck-Sr> i need to find the chipset of a thin client
| |
19:09 | after trying 3 different pc, different make, model, brand, the sound still drops out after about 4-6 minutes
| |
19:14 | <johnny> lspci in a terminal..
| |
19:24 | <Ahmuck-Sr> that shows the client chipset?
| |
19:24 | i was thinking it showed the server chipset

19:46 | <abeehc> Ahmuck-Sr: that's right if you are logged into the server ,it would show the server chipset
| |
19:46 | you need a client shell
| |
19:48 | https://help.ubuntu.com/community/UbuntuLTSP/ClientTroubleshooting#Using a shell SCREEN
| |
20:17 | <johnny> Ahmuck-Sr, yes.. a client terminal..
| |
20:17 | either on the virtual console
| |
20:17 | or in a debug term via LDM_DEBUG_TERMINAL
